Microflex’s preinsulated piping system, composed of a thermal insulation around a carrier pipe and covered by a “closed chamber “ protective casing, is therefore your best choice. Microflex piping is suitable for use in heating, cooling and sanitary applications and provides significant advantages such as, low-weight, hyper flexibility, robustness, and easy and rapid laying even over obstacles and around corners. System accessories can be mounted without any special tools. Our PE-Xa Central Heating carrier pipe (made from cross-linked polyethylene) is oxygen diffusion proof in accordance with DIN 4726. It can transport a large number of different liquids and is fully corrosion free. Microflex® is made available as a single, twin or quadruple piping system. It is manufactured free of CFCs. 1.2 Fields of Application • Heating • Hot Water Distribution • Supply to Individual Buildings • Distribution Inside Buildings • Local or Remote Heating Networks • Sanitary Water • Distribution of Potable and Non-Potable Water • Renewable Energy • • • • • Heat Pumps Biogas and Biomass Installations Combined Heat and Power (CHP) Pellet Fuels Geothermal Applications • Special Applications • • • • Transport of Chemicals Food Industry Cooling Systems Swimming Pools, Leisure Centres 1.3 Properties • • • • • • • • Versatility Oxygen Diffusion Barrier to DIN 4726 Low Weight Completely Corrosion Resistant Environmentally Friendly Manufacture Maintenance Free Long Life Expectancy Superior Quality Tel. + 32 (0)16 44 21 31 • Fax + 32 (0)16 44 03 68 [email protected] • www.microflex.be • www.wattsinsulation.com A Company of Watts Water Technologies EMEA B.V. mic_xxxxxx_technisch-handb_150223_ENG.indd 5 23/02/15 16:07 6 1.4 Structure of the Microflex System The Microflex piping system consists of three integrated components and is manufactured according to the EN 15632: 1-3 norm • Piping system with one pipe: UNO Corrugated twin wall outer casing (PE-HD) Microflex UNO PN 6 - PN 10 - PN 16 Carrier Pipe (cross-linked PE-Xa or PE-100) Insulation (cross-linked PE foam) Piping system with two pipes: DUO Microflex DUO PN 6 - PN 10 - PN 16 • Piping system with four pipes: QUADRO Microflex QUADRO 2 x PN 6 - 2 x PN 10 The Hyper Flexibility of the Microflex® Piping System 0,6 m - Placement of the pipe over obstacles and around corners is possible. - The inside bending radii of the different pipes are specified in the Product Range Tables (see section 2.1). Measurements are taken from the inside of the pipe. A reserve factor is taken into account. - For example: two PE-Xa pipes of Ø 40 mm can form a curve with an inside radius of 0.6m (see picture).

PE-Xa stands for cross-linked PE, whereby cross-connections between the PE molecules are formed. The resulting molecule is more resistant to extremes of temperatures/pressures and chemical attack. Thermal Properties The life expectancy of the pipe is highly dependent on a combination of pressures and temperatures. The carrier pipe has a life expectancy of 50 years, as detailed in the enclosed table, when the pressure and temperature are kept constant and thus meets the ISO 15875 norm. Life expectancy PE-Xa pipes at constant pressure and temperature (safety factor C=1,25) Temperature Life expectancy This table serves as a general guideline. In practice, it’s necessary to take into account widely varying pressures and temperatures. SDR 11 7.4 operating pressure bar The pipes are, in normal operation, able to withstand operating temperatures and pressures of 85°C / 6 bar for heating and 85°C / 10 bar for sanitary installations. For a short time, the material is also resistant to temperatures of 95°C. °C years 10 50 17.1 27.1 20 50 15.1 24.0 30 50 13.4 21.3 40 50 11.9 18.9 50 50 10.6 16.8 60 50 9.5 15.0 70 50 8.5 13.4 80 50 7.5 12.0 Most chemicals have no influence on the pipe, even at elevated temperatures. Typically, plastics that are exposed to chemical substances are prone to physical changes in their properties, such as, swelling or dissolution of the polymers. Due to the chemical bonding of the polymer chains, PE-Xa pipes (cross-linked PE) are more resilient in that respect than pipes of non-crosslinked PE. In order to assess the resistance to different materials changes in the tensile and elongation characteristics were monitored. In a pressurised piping system the resistance to unknown chemicals cannot generally be extrapolated from experience of known chemicals. For this, durability tests with the unknown chemicals in test piping are required. For the list of Chemical Resistance, see Appendix, section 5.9. 90 50 6.8 10.9 High Abrasion Resistance Chemical Resistance PE-Xa pipes provide an enhanced abrasion resistance and durability. Pipes conveying aggressive sludge at fairly high velocities do not suffer internal erosion. Pipe Roughness The smooth bore offers less resistance to flow than conventional pipes resulting in excellent flow characteristics with minimal flow loss without formation of any sedimentary deposits. Environmentally Friendly PE-Xa pipes are certified to comply with international potable water quality requirements such as DVGW, WRAS and ACS (copies of the certificates are available on request). The pipe imparts neither taste nor odour and is non-toxic. Consequently it is ideally suited for different branches of the food industry.

In addition to the excellent insulating properties, the closed-cell structure of the material ensures that there is only minimal water absorption. The material is CFC free. Durability The closed cell structure ensures optimal quality preservation with constant insulation performance throughout its long service life. C fre The shape memory of the cross-linked polyethylene foam makes it permanently elastic and ensures the continuance of the initial insulation performance, even after repeated rolling, unrolling and bending of the system. The durable insulation performance makes the Microflex pipe therefore extremely resistant to aging. e CF free Insulation Material Properties Temp Density Standard Value Unit ISO 845 28.0 kg/m3 Tensile Strength Longitudinally at Fracture @ 23 °C ISO 1926 299.0 kPa Longitudinal Elongation at Fracture @ 23 °C ISO 1926 122.0 % 100 °C ISO 2896 <1 % ISO 8301 0.040 W/mK Thermal Stability: Max Temperature Water Absorption Thermal Conductivity @ 40 °C 1.7 Corrugated PE-HD Double-Walled Casing The outer cover made from PE-HD following the “closed chamber” principle, protects the inner pipe as well as the insulating material from external impacts. The ribs of the corrugated outer cover are completely closed; water ingress due to superficial damage to the outer cover is therefore impossible. Due to the corrugated structure, the piping has longitudinal flexibility and resistance to impacts. Microflex piping is very robust and resistant to aggressive substances.

Points of Attention for Assembly 25 3.1 Transport and Storage Microflex pipelines are supplied in coils with a maximum length of 100 metres. Pipe ends are sealed with protective end caps to prevent the entry of foreign material and should not be removed during transport or storage. Microflex pipelines must be transported upright. Whilst in storage, care must be taken to ensure that the PE-Xa carrier pipe is protected from sunlight and that no undesirable deformation of the coil is occurring. Pipes must be transported and stored in such a way that sharp objects, like stones and tree roots cannot damage them. Pipes must not be dragged along the ground. Unloading and transport to the end location should only be done by a forklift truck. Only nylon or textile straps should be used for fastening the coils during transport. 3.2 Pipe Cutting Microflex carrier pipes need to be cut at a right angle with a pair of PE-X scissors. This way, the carrier pipe will be closely mated to the coupling and therefore reduce the risk of leakage. The pipe end-cuts must be deburred with an appropriate tool and the resulting swarf removed completely. Residual burrs on the pipe ends and loose swarf could prevent the coupling from sealing correctly and consequently leakage might occur. It is possible that swarf could eventually block other system components such as heat exchangers. Microflex Quadro pipes are susceptible to deformation (kinking of the PE-X carrier pipes) after cutting. The smaller sizes are especially susceptible to this problem. We advise to pressure test every cut pipe using compressed air. 3.3 Instructions for Laying Microflex Pipes in Soil Utility Trench Profiling Before the excavation work can begin, one must check that no conflict may arise with existing and/or planned lines or structures. Excavation works must be carried out in the approved manner, according to the rules and regulations of local authorities. Prior permission is very often required. Up to a trench depth of 120cm, we recommend digging a trench with vertical sidewalls; deeper than 120cm we recommend a V-shaped trench. The profile of the utility trenches must conform to the Microflex guidelines for laying pipes. Particular attention must be paid to ground frost depth. ATTENTION: Minimum laying temperature for Microflex pipes: -5°C.

Loading up to SLW60 according to DIN 1072 when covered at minimum 900mm. The static calculations of buried pipes are according to ATV-DVWK-A127. Laying Microflex Pipes in Soil Microflex pipes are rolled up for easy storage and transport. As a result of this rolling up, the pipes are under mechanical stress. Please take care that untethered pipe ends don’t whip back when untying the textile straps. Given that all windings are individually bound, we strongly recommend removing every strap sequentially to gradually release the inbuilt tension rather than removing them simultaneously. The pipes may be laid into the trench directly from the coil. This may only be done by pulling the carrier pipes (never pull the casing). When laying larger dimensions and lengths, pulling devices such as winches or tail-end rollers may be used. Always connect these devices to the carrier pipe. Carefully place the Microflex pipeline on a compacted 10cm bed of sand on the bottom of the trench. The sand bed must be evenly laid to provide uniform support for the pipeline. This has a decisive influence on the compressive stress of the piping system. Take care that the pipe is not dragged along the ground or is damaged by sharp objects (in order to prevent damage to the outer casing). The bending radii (see Product Range, section 2.1) must not fall below the prescribed minimum either during installation or in the final position of the pipeline. Pipes must be laid in a serpentine course in order to minimise the expansion/contraction forces on the pipe. In order to keep the pipes in position during laying, cover them at regular intervals with sand.

The technique consists of making a borehole and pulling the Microflex pipeline through. For the correct process of Horizontal Directional Boring we refer to the guidelines of this technique. Before pulling the Microflex pipeline through the borehole there are some points of attention: - Drill hole Diameter. Increase the reamer’s diameter according to the outer diameter of the Microflex pipe to achieve an optimal result. - Connecting. When coupling the Microflex pipe to the reamer, ensure that both the PE-Xa carrier pipe and the outer casing are fastened. - Pulling. It is important that the piping is ready in its entirety so that the pulling through can happen in one smooth, fluid movement. For this we recommend to remove every nylon strap and to unroll the pipe completely. Rotation or twisting of the pipe during the pulling operation must be avoided at all cost. This way no torsional forces will be exerted on the piping. - Traction forces. The Maximum pulling forces for the different PE-Xa medium pipes are given in the table below. Attention: these values are for UNO models only. For DUO models, please double the value. Outer Pipe Diameter UNO Maximum Traction Forces per Pipe (kg) 25 150 32 200 40 300 50 400 63 400 75 400 90 400 110 400 125 400 3.4 Mounting onto Walls or Ceilings Max.100 cm For this purpose, the pipe must be supported every meter along its entire length because of its inherent flexibility. To avoid sagging, the pipe must be tied with straps to a supporting structure. 3.5 Guidelines for Pipe Laying on the Ground Surface wall mounting If the pipeline is laid on the ground, points of support must be provided to prevent slipping away. All objects on the ground that may cause damage to the outer casing of the pipe need to be removed. On uneven ground, the pipe should be tied at intervals of about 25m, and care must be taken to ensure that the pipes are well supported. For this purpose a supporting structure can be set up. Attention: Our pipes have limited UV resistance. Therefore it is necessary to protect the pipe against UV-radiation when they are laid at their final aboveground placement.

This will help with the feedthrough sealing and stability of the pipe. Clean the Micro Seal and the outer casing before assembly. Any contamination can have an adverse impact on the sealing between the casing and Micro Seal chains, with water intrusion as the worst result. Also check that the stainless steel bolts threads have been lubricated with copper grease in order to avoid the risk of galling. When applying the Micro Seal chains around the outer casing check the distance between the different pressure plates is uniform to ensure an even stress distribution on the pipe. To prevent over-torqueing of the bolts, don’t use electrical tools. For further information, refer to the Operating Instructions, section 4.1. 3.7 MMDV Wall Feedthrough (Surface/Above Ground Use) This wall sleeve consists of a corrugated HD-PE pipe and a shrink sleeve. The corrugated HD-PE pipe can be either cemented into concrete or mortared into the wall opening (the correct sizes can be found in the table below). Approximately 100mm of the corrugated pipe must protrude to the outside in order to seal the pipe with the Microflex shrink sleeve. Attention: the wall thickness must be less than or equal to 400mm. When heating the shrink sleeve, take care not to burn/damage the outer casing or the shrink sleeve. Art.

A dust cap provides for a dust tight closure of the pipe. As the carrier pipes are constantly subjected to a double-action force (thermal and longitudinal expansion/contraction), it is necessary to anchor it to a support system using fixing points. Fixing points limit the effects of these forces. Non-usage of these fixing points can lead to serious damage to the pipe network and to the connection with the source or user. The use of fixing points is mandatory for warranty eligibility. 3.9 Shrink Caps Type MK A shrink cap prevents ingress of water between the outer casing and the insulated carrier pipe. After being slipped over the carrier pipe and the outer casing, it can be warmed up for fixation around the pipe. Use a heat gun or mini torch to gently shrink the cap. Attention: Using too high a temperature can damage the shrink cap or casing. 3.10 EPDM Rubber End-Caps Use the correct tool for the cutting of the EPDM Rubber end-cap (sharp knife or scissors). Under no circumstances should the end-cap be sawn. The cut should be straight and neat. Damages, like splits or tears on the cut section, can cause leaks. Use only water for cleaning or wetting the end-cap or pipe. The use of a lubricant (soap, grease or oil) can cause damage to the various parts. The three seal ridges must grip into the ridges of the outer casing in order to obtain a watertight seal.

The following points need to be adhered to obtain a correct mounting: - Cutting of the PE-Xa Carrier Pipe. It is essential to cut the PE-Xa pipe at a right angle with a pair of PE-X scissors or a pipe cutter. The PE-Xa carrier pipe needs to touch the flange of the coupling completely in order to have a good seal. If this is not the case (because of a sloping cut or because the support pipe is not inserted sufficiently), a watertight seal cannot be guaranteed. - Deburring of the Cut PE-Xa Carrier Pipe. It is essential to deburr every cut carrier pipe with an appropriate tool. Residual burrs cause extra friction in the pipe during assembly of the couplings and swarf from inadequately cleaned pipe end-cuts may cause pressure loss through poor sealing. Other components, such as heat exchangers, may also encounter problems when deburring and swarf removal is not properly done. - Pay Attention to the Direction of the Clamping Ring. Ensure that the notch on the inside of the clamping ring is facing the fitting. If not, the coupling won’t be leak tight. - Stainless Steel Bolt, Nut and Washer. Always use a stainless steel bolt, nut and washer for tightening the coupling and make sure that they are lubricated with copper grease. Non-usage of copper grease can lead to galling of the bolts with leakage as a result of incomplete tightening. - Watertight Sealing. After half an hour, one must again re-tighten the bolts in order to ensure a watertight seal. - Pressure Test. The pressure test procedure is obligatory before closing the trench 3.12 Self-Regulating Heating Cable Cable Preparations Use a sharp cutter (Stanley knife) to score the outer insulation sheath of the heating cable to bare the conductor cables. Take care not to damage the conductor cables themselves. The heat-shrink sleeves are applied with a heat source (hot air gun or equivalent). Ensure the heat is applied uniformly to obtain a good seal. Using too high a temperature can damage the cable insulation. Always insulate the end of the cable. Under no circumstances should the two connectors be allowed to touch one another. A short-circuit will occur otherwise. The operation of the heating cable is explained in the Appendix, section 5.11. Connections When connecting the heating cable to the mains power via the MVTH and MVBOX, the electricity must be turned off before connecting the various conductors. This way the risk of electrocution is avoided. Keep in mind that the MVTH can operate a heating cable with a maximum total length of 100m. If this length is exceeded, the operation of the thermostat can no longer be guaranteed. The cable would be heating irregularly, with potential large losses as a result. Connect the corresponding conductors and earthing with each other inside the MVBOX. To check that the conductors/earthing are securely clamped, pull the insulation of the conductors/earth using pliers. The attachment of the MVTH and MVBOX must be performed according to the included installation instructions.

This method makes the assembly of the terminal connections in the casing much easier. When supplying the insulation kits, both insulation halves are already connected via screw connections. Before separation, the shells can be cut along a chosen line to obtain the desired diameter. Cutting needs to be done in a straight line to avoid any chance of leakage. The correct mounting of type MK shrink caps (see section 4.3) will minimise the chance of leakage. The use of MK heat shrinkable caps is compulsory to be eligible for the warranty. Instructions for the assembly of the couplings can be found in sections 3.11 and 4.5. Cut the bitumen strips to suit the pipe casing outer diameter. Before applying, check that the outer casing is dry to ensure a good contact. After cutting to the desired size, apply the bitumen strips around the carrier pipe. Make sure that the connections are properly covered. Before placing a pipe in one of the shells, ensure sealant is applied to the grooves as described in the instructions in section 4.7. Apply the sealant uniformly along the flanges on the top and bottom of the casing before tightening the stainless steel bolts. It is extremely important that the insulation kits are properly sealed. Depending on the chemical composition of the soil, rising groundwater may be slightly acidic and therefore mildly corrosive. The ingress of this groundwater could eventually cause corrosion of couplings, sleeves, connections etc. and might lead to leakages. MR24116075 When using a (double) T-piece with an outer casing diameter of 160mm to an outer casing diameter of 90 or 75mm, one can use the MR24116075. This set comprises an outside casing (160mm) with interior insulation (but no carrier pipe) and a shrink sleeve (type MK2500). The reducer is pressed into the insulated T-piece kit. Slide the shrink cap over both protruding ends, ensuring that both are well covered. Use a torch or hot air gun to slowly heat the shrink cap. Make sure to use the heat gun on a medium heat setting to gently shrink the sleeve half over the insulation kit and half over the MR reducer kit.

It is equipped with 6 marked entries. Each of them can be cut off to suit various opening sizes (125, 160 or 200mm). The installation and points of attention are as for the insulation kits. After installing the chamber and completing the pipe connections it is recommended to remove the manhole cover and perform an internal inspection of the installation. It is also recommended to connect shut-off valves to allow for future alterations to the pipe network. Obviously one must take precautions to prevent water infiltration in order to minimise wear and corrosion of the different internal parts. Shrink caps and couplings need to be installed in the proper way (see sections 4.3, 4.4, and 4.5). Before closing the inspection chamber, make sure that all pipe connections and fittings are secure. It is necessary to uniformly apply sealant to the upper edge of the chamber body part at a thickness of about 10mm by 10mm wide before affixing the cover. This will prevent any water infiltration. The pitched top is secured on the body part by use of 6 stainless steel bolts. The threads of the bolts need to be lubricated with copper grease before tightening. This is to prevent galling. Once the pitched top has properly been installed, the lid can be carefully turned clockwise. Do not damage the black gasket between body and top cover. Do not use excessive force when tightening the bolts. The carrier pipes can exert lateral forces on the inspection chamber due to expansion/contraction. These forces may result in a slight deformation/movement of the chamber. Therefore it is recommended to provide additional concrete reinforcement to the edges/sides of the chamber. If the chamber is subject to a high traffic load, it is recommended to provide appropriate additional concrete reinforcement. These concrete slabs or rings must be placed on a bed of stabilised cement (see picture below). ATTENTION: Consider local frost depths when determining the minimum coverage.

The report of this test , fully completed and signed, has to be send to our production plant. 1. Pressure test constitute contractually agreed auxiliary work essential to the accomplishment of the contract and also form part of the contractor’s performance without being stated in the performance specification. Prior to concealing, fill the finished pipework with water, taking care to avoid air locks. The pressure test must be conducted in two parts, starting with the preliminary test, followed by the main test. 2. Preliminary test The preliminary test involves applying a test pressure equal to 1.5 times the admissible operating pressure. This pressure must be regenerated twice within the space of 30 minutes at intervals of 10 minutes. Following a rest period of at least 30 minutes at full pressure, the test pressure must not have fallen by more than 0.6 bar (0.1 bar every 5 minutes). Leakages must not occur at any point in the system being tested. 3. Main test The main test has to be conducted immediately after the preliminary test. The test takes 2 hours. At the end of this period, the test pressure recorded after the preliminary test must not have fallen by more than 0.2 bar. Leakages must not occur at any point in the system being tested. bar / psi In order to validate the pressure test, send the report to: WATTS INDUSTRIES S.r.l.

The correct implementation and documentation of the pressure test are requirements for the warranty to be valid. Make sure that the pipes are fully covered with sand (granular range of 0-3 mm). Backfilling should be in layers of about 20 cm and compacted by hand. Care should be taken to remove any sharp objects from the backfill material. When the backfill depth is about 50cm above the top of the pipe, a vibrating tamper may be used to compact the remainder of the soil (measured from the top of the pipe). There should also be a warning tape bearing the legend “water pipe” laid directly above the buried piping. 3.17 Before Usage For hygiene reasons, we recommend rinsing all sanitary pipes for 15 minutes before use.

Operating Instructions 4.1 MICRO SEAL Wall Feedthrough (Subterranean Use) 35 Centre the pipe in wall opening or casing. Make sure the pipe will be adequately supported on both ends. Micro Seal feedthrough seals are not intended to support the weight of the pipe. Loosen the pressure plate bolts just enough so the links can move freely. Connect both sections of the feedthrough around the pipe. Ensure all bolt heads are facing the installer. Extra slack or sag is normal. Do not remove any links if extra slack exists. Note: On smaller diameter pipe, links may need to be stretched. Slide the Micro Seal assembly into the annular space (ring-shaped cavity between the pipe and the wall). For larger size chains, start inserting the feedthrough at the 6 o’clock position and work both sides up toward the 12 o’clock position in the annular space. Manually tighten using a spanner or wrench only. Do not tighten any bolt more than 4 turns at a time. Tighten the bolts in a crisscross pattern or sequence until all bolts have been uniformly secured. Repeat this after a couple of hours to ensure long-term tightness of the bolts.

Use the correct tool for the cutting (sharp knife or scissors). The cut has to be straight and neat to ensure tightness of the rubber end-cap. Damages, like splits or tears on the cut section, can cause leaks. The pipe ends and the rubber end-caps must be cleaned only with water before installation. Fold the sealing sleeve back. Put the rubber end-cap over the carrier pipe and push it against the insulation. If needed, wet the carrier pipe with water. Do not use soap, grease or oil for lubrication. Pull the sealing ridges onto the outer casing of the pipe. The three seal ridges must grip into the ridges of the outer casing. Insert the provided tie wrap between the two rings. Pull the end of the tie wrap with a rotating movement tight around the cap using universal pliers.

To calculate the heat loss one has to take into account the following factors: - λ insulation: 0.040 W/mK at 40°C - λ ground: 1 W/mK - λ PE-Xa pipe: 0.35 W/mK - Depth of cover over top of pipe: 80cm In sections 5.4 to 5.7 the heat loss tables/graphs for the different Central Heating models (UNO, Uno Primo, Duo and Duo Primo) are listed. These tables/graphs list the various diameters available for the pipes and are cross-referenced to the temperature differential with respect to the ground. By comparing a known pipe size (with a known media temperature) and knowing the local ground temperature, the ΔT column lists the heat loss in the pipe per meter. By multiplying this heat loss per meter with the total pipe length, you arrive at the total heat loss for the entire pipe.

Typically, plastics that are exposed to chemical substances are prone to physical changes in their properties, such as, swelling or dissolution of the polymers. Due to the chemical bonding of the polymer chains, PE-Xa pipes (cross-linked PE) are more resilient in that respect than pipes of non-crosslinked PE. In order to assess the resistance to different materials changes in the tensile and elongation characteristics were monitored. In a pressurised piping system the resistance to unknown chemicals cannot generally be extrapolated from experience of known chemicals. For this, durability tests with the unknown chemicals in test piping are required.

It is also covered by a plaited, tin-coated copper cord. This plaiting provides the earthing (safety conductor) for the heating cable, complies with prevailing safety standards (VDE 0100) and is fitted with an additional mechanical protection. Proven lifespan Self-regulating heating element These self-regulating heating cables have been intensively tested in our laboratories using international standard tests and recognised scientific methods and procedures. These tests found that the self-regulating heating cable has a lifespan of over 40 years. Electric insulation mantle Safety plait in tin-coated copper External safety cover Licenses All self-regulating heating cables are manufactured in accordance with the strictest quality norms and are subjected to ongoing quality controls. They are VDE-certified as well as with a variety of production, control and other licenses from many countries. Parallel circuits Schematic diagram The current flows between two parallel copper conductors, regardless of where the heating cable is and right through the semiconducting, molecularly refined heating element. The electrical circuit diagram is similar to a parallel circuit in many temperature-dependent resistances. Heating power The system’s straightforward design and even simpler installation process will save you considerable expense. The heating cable is always connected to a 230 VAC output, regardless of its length. Operation The heating element consists of a specially formulated, molecularly refined plastic cover embedded with carbon particles which generate electrical currents between two parallel copper conductors. When the temperature rises, the plastic expands due to molecular expansion. Ambient temperature The carbon particles move further and further apart, resulting in the interruption of the electrical currents and a rise in the electrical resistance of the heating element. The current draw and the heating capacity fall proportionally. 1 2 3 1 In the cold sections of the heating cable, the structure of the plastic will draw together, generating a large number of electrical currents through the carbon particles. The current is converted into heat in the heating element. 2 In the warmer sections, the structure of the plastic expands and progressively interrupts the currents in the carbon particles. This increases the resistance and reduces the current draw and thus the heating capacity. 3 In the hot sections, the expansion of the plastic structure breaks the currents almost entirely. This creates a very high electrical resistance and the heating capacity falls to almost 0. When the element cools, the process is reversed and the heating capacity rises in response to low temperatures. The molecular refinement of the heating element gives it duroplastic properties, making the expansion behaviour at molecular level exactly reproducable, even under fluctuating temperatures. The self-regulating properties of the heating cable are thus incorporated into the material itself. Thanks to this self-regulation, the heating cable responds to temperature fluctuations along the entire length of the system. Energy conservation Because the heating capacity adjusts to local temperatures, energy consumption is always adapting to prevailing requirements. The heating cables therefore save energy and costs through self-regulation. Safe and reliable Due to these self-regulating properties, the system cannot overheat or burn through, even if the heating cable overlaps.
